For each client, our process begins with setting the destination of Operational Excellence. At Duggan Associates, Operational Excellence has a very clear definition:


“When each and every employee can see the flow of value to the customer, and fix that flow before it breaks down.” SM

The Eight Principles of Operational Excellence

From there, we follow the eight principles of Operational Excellence outlined in the book  Design for Operational Excellence by Kevin J. Duggan:


First Principle: Design Lean Value Streams

Second Principle: Make Lean Value Streams Flow

Third Principle: Make Flow Visual

Fourth Principle: Create Standard Work for Flow

Fifth Principle: Make Abnormal Flow Visual

Sixth Principle: Create Standard Work for Abnormal Flow

Seventh Principle: Have Employees in the Flow Improve the Flow

Eighth Principle: Perform Offense Activities


Value Stream Design

For application of the process in certain settings, such as the office or complex areas in manufacturing, we teach unique guidelines, including:


8 Guidelines for Manufacturing Value Streams

6 Guidelines for Creating Flow through Shared Resources

9 Guidelines for Office Value Streams

10 Guidelines for Mixed Model Pacemaker

8 Guidelines for the Supply Chain




Our approach enables organizations of any size, in any industry, to achieve Operational Excellence and sustain business growth in months – not years.
